Arch Capital Group ACGL
Arch Capital Group scores good on business quality (7.2 of 10). Here is why, in plain words, and what our sealed record shows.
Why it matters
- What Arch Capital Group does
Arch Capital Group writes property, casualty, and mortgage insurance and reinsurance worldwide, collecting premiums from individuals and corporations to shoulder risk. The company is deploying capital aggressively, using its $6.1 billion in free cash flow to fund buybacks of $3.4 billion while expanding its underwriting portfolio.
- What it does best
Arch excels at generating high returns on equity, posting an ROE of 19.5% that outpaces peer AXS at 17.3%. This efficiency stems from disciplined underwriting cycles and low debt-to-equity of 0.1x, insulating its underwriting margins from credit shocks.
- The main risk
Catastrophic weather events and unexpected property claims remain the primary threat, capable of instantly reversing underwriting income if reinsurance pricing fails to cover severity.
Quality, check by check
